BACKGROUND This study examined the refractive and visual outcome of wavefront-optimized laser in situ keratomileusis (LASIK) in eyes with low myopia and compound myopic astigmatism ≤ 0.75 diopter (D). METHODS 153 eyes from 153 consecutive myopic patients (74 male, 79 female; mean age at surgery 40.4 ± 10.4 years) who had a preoperative refractive cylinder ≤ 0.75 D and a manifest sphere betwee...

PURPOSE To demonstrate that relatively simple third-order theory can provide a framework which shows how peripheral refraction can be manipulated by altering the forms of spectacle lenses. METHODS Third-order equations were used to yield lens forms that correct peripheral power errors, either for the lenses alone or in combination with typical peripheral refractions of myopic eyes. These resu...

purpose : to assess the visual and refractive outcomes after implantation of toric implantable collamer lens (t-icl) in compound myopic astigmatism methods : in this prospective study, 28 eyes with manifest refraction spherical equivalent (mrse) errors of -10.94±4.09 diopter (d) and mean cylindrical errors of -3.47±1.39 d underwent t-icl implantation. six months after surgery, best corrected an...

purpose: to determine the accuracy of photorefraction and autorefraction as compared to cycloautorefraction and to detect the repeatability of photorefraction. methods: this diagnostic study included the right eyes of 86 children aged 7‑12 years. refractive status was measured using photorefraction (plusoptix so4, gmbh, nürnberg, germany) and autorefraction (topcon rm800, usa) with and without ...

PURPOSE Relatively little data exist regarding the outcomes of children with primary infantile glaucoma presenting with acute corneal hydrops. The aim of our study was to determine the surgical outcome of children of infantile glaucoma who presented with acute corneal hydrops. METHODS In total, 38 eyes of 31 consecutive children of infantile glaucoma presented with acute corneal hydrops who u...
